Human Mammary Smooth Muscle Cells

Description

Human Mammary Smooth Muscle Cells (HMSMCs) are primary cells isolated from the smooth muscle layer surrounding lactiferous ducts in healthy human breast tissue. These spindle-shaped cells exhibit a classic elongated morphology characteristic of smooth muscle and are cryopreserved at low passage to retain physiological attributes. These cells are positive for α smooth muscle actin (αSMA). HMSMCs display contractile behavior in response to calcium-mediated stimuli, recapitulating in vivo ductal contraction and milk ejection mechanisms. These cells are supplied frozen, ready for thawing and experimental use, and should be used within recommended early passages to preserve phenotype and function. Each lot undergoes rigorous screening and isolation procedures, and is rigorously tested to ensure it is free of contamination from HIV-1, HBV, HCV, Syphilis, Mycoplasma, Fungi, Yeast, and Bacteria.
